DURABLE PROTECTION FOR INFRASTRUCTURE DEVELOPMENT
24.07.2023   |   Protective Coatings

Mention paint and the first thing that usually comes to mind is to give the space a new look. However, paint and coatings offer a myriad of functional solutions beyond just enhancing wall surface aesthetics. As mentioned, besides providing a dash of colour, paint and coatings provide a layer of added protection to surfaces. Take for instance infrastructures such as bridges, train stations and airports. These projects have extremely high safety requirements and protocols – and are meant to last a lifetime. Being constantly subjected to demanding conditions and the harsh environment, it is only vital that they be protected to prevent any untoward incidents. For instance, unprotected steel structures are exposed to the elements, which may lead to corrosion, and this will affect the structural integrity. Hence, it is important to apply tried and tested protective coatings for longevity and reduced maintenance costs, in addition to enhance the structure to prevent it from rust. To assure peace of mind for its users, Nippon Paint Protective Coatings, the professionals preferred solutions, always adhere to stringent quality controls. They also comply with ISO 12944, an international standard on corrosion protection of steel structures by protective paint systems. Thus, you can enjoy quality in every drop to fulfil your project’s purpose. Where to begin? First, when selecting the best coating system for your project, you must consider the environment and then the desired durability – as outlined in ISO 12944. Befitting its status as “Asia’s No. 1 Total Coatings Expert”, Nippon Paint offers all-inclusive products catering to a wide array of solutions, from basement to roof and every layer in between, from architectural and industrial coatings to protective coatings and many more! 1. Determine the environment   Table 1: Atmospheric-corrosivity categories and typical environments Corrosivity category Exterior Interior C1 (very low - Heated buildings with clean atmospheres (e.g. offices, shops, schools, hotels) C2 (low) Atmospheres with low level of pollution: mostly rural areas Unheated buildings where condensation can occur, e.g. depots, sports halls C3 (medium) Urban and industrial atmospheres, moderate sulphur dioxide pollution; coastal areas with low salinity Production rooms with high humidity and some air pollution (eg. food processing plants, laundries, breweries, dairies) C4 (high) Industrial areas and coastal areas with moderate salinity Chemical plant, swimming pools, coastal ship and boatyards C5 (very high) Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity Buildings or areas with almost permanent condensation and with high pollution CX (extreme) Offshore areas with high salinity, industrial areas with extreme humidity and aggressive atmosphere and subtropical and tropical atmospheres Industrial areas with extreme humidity and aggressive atmosphere Corrosivity categories can also be estimated by considering the combined effect of the following environment factors: yearly time of wetness, yearly mean concentration of sulphur dioxide and yearly mean deposition of chloride. The loss values for the corrosivity categories are identical to the those given in ISO 9223.   Table 2: Categories for water and soil Category Environment Examples of environment and structures IM1 Fresh water River installations, hydro-electronic power plants IM2 Sea or brackish water Immersed structure without cathodic protection (e.g. harbour areas with structures like sluice gates, locks or jetties) IM3 Soil Buried tanks, steel piles, steel pipes IM4 Sea or brackish water Immersed structures with cathodic protection (e.g. offshore structures) Note: For corrosivity category IM1 and IM3, cathodic protection can be used with a paint system tested accordingly   2. Desired durability   Durability Years to first major maintenance Low (L) Up to seven years Medium (M) Seven to 15 years High (H) 15 to 25 years Very high (VH) More than 25 years Once you have determined the environment and desired durability, it is time to choose an ISO 12944-recommended coating system for your project. There is an extensive range of coating systems offered by Nippon Paint which are readily available in the market today. The systems cater to both atmospheric and immersion corrosion condition and Nippon Paint Protective Coatings are specially formulated solutions that protect surfaces that are highly prone to corrosion, rust and the other detrimental effects from the environment.

THE ULTIMATE ANTI-CORROSION PROTECTION FOR YOUR STEEL STRUCTURES
21.07.2023   |   Protective Coatings

Corrosion is a costly problem. A study by the worldwide corrosion authority NACE International indicated that the global cost of corrosion is estimated to be US$2.5 trillion, equivalent to 3.4% of the world’s Gross Domestic Product (2013)¹; Malaysia’s annual cost of corrosion is about RM6.7 billion from RM207.4 billion of GDP². By definition, corrosion is natural process that converts a refined metal into a more chemically stable form such as its oxide, hydroxide or sulphide state, which resulted in deterioration of the  material. It can occur all the time and appears in different forms at  different environments. When exposed to open air, immersed in water or surrounded by soil, all unprotected steel is subject to corrosion and consequently will undermine a building’s structural integrity. Therefore, corrosion protection is essential as it will optimise the performance and maximise the lifetime of the steel structure to which it is applied.  ISO 12944 CORROSION PROTECTION It is important to note that selecting a coating system that complies with ISO 12944 can provide you with the confidence and peace of mind that the corrosion protection you specify will fulfil your project and purpose. ISO 12944 standard aims to assist engineers and corrosion experts in adopting best practices in corrosion protection of structural steel in new constructions. It is widely adopted and globally accepted industry standard, recognised by specifiers worldwide. When selecting the best coating system for your project, you must first consider the environment and then the desired durability. 1. Determine Environment It is crucial to determine the environment surrounding your project. This can be classified as atmosphere category (where the corrosion can occur in interior and exterior of the building), and immersed category (for buildings immersed in water or buried in soil).   Table 1: Atmospheric-corrosivity categories and typical environments. CORROSIVITY CATEGORY EXTERIOR INTERIOR C1 (Very Low) - Heated buildings with clean atmospheres (e.g. offices, shops, schools, hotels). C2 (Low) Atmospheres with low level of pollution: mostly rural areas. Unheated buildings where condensation can occur, e.g. depots, sports halls. C3 (Medium) Urban and industrial atmospheres, moderate sulphur dioxide pollution; coastal areas with low salinity. Production rooms with high humidity and some air pollution (e.g. food-processing plants, laundries, breweries, dairies). C4 (High) Industrial areas and coastal areas with moderate salinity. Chemical plants, swimming pools, coastal ships and boatyards. C5 (Very High) Industrial areas with high humidity and aggressive atmosphere and coastal areas with high salinity. Buildings or areas with almost permanent condensation and with high pollution. CX (Extreme) Offshore areas with high salinity, industrial areas with extreme humidity and aggressive atmosphere and subtropical and tropical atmospheres. Industrial areas with extreme humidity and aggressive atmosphere. Note: Corrosivity categories can also be estimated by considering the combined effect of the following environment factors: yearly time of wetness, yearly mean concentration of sulphur dioxide and yearly mean deposition of chloride (see ISO 9223). The loss values used for the corrosivity categories are identical to those given in ISO 9223. Table 2: Categories for water and soil. CATEGORY ENVIRONMENT EXAMPLES OF ENVIRONMENT AND STRUCTURES IM1 Fresh Water River installations, hydro-electronic power plants. IM2 Sea or brackish water Immersed structures without cathodic protection (e.g. harbour areas with structures like sluice gates, locks or jetties). IM3 Soil Buried tanks, steel piles, steel pipes. IM4 Sea or brackish water Immersed structures with cathodic protection (e.g. offshore structures). Note: For corrosivity category IM1 and IM3, cathodic protection can be used with a paint system tested accordingly. 2. Desired Durability Next to be considered is the durability or performance of the coating system before first major maintenance. Minor maintenance should be carried out regularly in order to achieve the required lifespan of the coating system to first major maintenance. Common durability considerations include design of the structure, conditions during application, time to first maintenance and accessibility for maintenance.   DURABILITY YEARS TO FIRST MAJOR MAINTENANCE Low (L) Up to 7 years Medium (M) 7 to 15 years High (H) 15 to 25 years Very High (VH) More than 25 years   3. Select ISO 12944 compliant coating system  Once you’ve determined the environment and desired durability, it’s time to choose an ISO 12944 compliant coating system for your project. There are extensive ranges of coating systems available in the market today, catering to both atmospheric and immersion corrosion categories, for carbon steel to hot dip galvanised steel and so forth.
